Add some simple KUnit tests for the nh() function.
These replace the test coverage which will be lost by removing the
nhpoly1305 crypto_shash.
Note that the NH code also continues to be tested indirectly as well,
via the tests for the "adiantum(xchacha12,aes)" crypto_skcipher.

Add a test suite for the POLYVAL library, including:
- All the standard tests and the benchmark from hash-test-template.h
- Comparison with a test vector from the RFC
- Test with key and message containing all one bits
- Additional tests related to the key struct

Add the following test cases to cover gaps in the SHAKE testing:
- test_shake_all_lens_up_to_4096()
- test_shake_multiple_squeezes()
- test_shake_with_guarded_bufs()
Remove test_shake256_tiling() and test_shake256_tiling2() since they are
superseded by test_shake_multiple_squeezes(). It provides better test
coverage by using randomized testing. E.g., it's able to generate a
zero-length squeeze followed by a nonzero-length squeeze, which the
first 7 versions of the SHA-3 patchset handled incorrectly.

Add a SHA3 kunit test suite, providing the following:
(*) A simple test of each of SHA3-224, SHA3-256, SHA3-384, SHA3-512,
SHAKE128 and SHAKE256.
(*) NIST 0- and 1600-bit test vectors for SHAKE128 and SHAKE256.
(*) Output tiling (multiple squeezing) tests for SHAKE256.
(*) Standard hash template test for SHA3-256. To make this possible,
gen-hash-testvecs.py is modified to support sha3-256.
(*) Standard benchmark test for SHA3-256.
[EB: dropped some unnecessary changes to gen-hash-testvecs.py, moved
addition of Testing section in doc file into this commit, and
other small cleanups]

Add a KUnit test suite for BLAKE2s. Most of the core test logic is in
the previously-added hash-test-template.h. This commit just adds the
actual KUnit suite, commits the generated test vectors to the tree so
that gen-hash-testvecs.py won't have to be run at build time, and adds a
few BLAKE2s-specific test cases.
This is the replacement for blake2s-selftest, which an earlier commit
removed. Improvements over blake2s-selftest include integration with
KUnit, more comprehensive test cases, and support for benchmarking.

Add a KUnit test suite for the Poly1305 functions. Most of its test
cases are instantiated from hash-test-template.h, which is also used by
the SHA-2 tests. A couple additional test cases are also included to
test edge cases specific to Poly1305.

Add hash-test-template.h which generates the following KUnit test cases
for hash functions:
test_hash_test_vectors
test_hash_all_lens_up_to_4096
test_hash_incremental_updates
test_hash_buffer_overruns
test_hash_overlaps
test_hash_alignment_consistency
test_hash_ctx_zeroization
test_hash_interrupt_context_1
test_hash_interrupt_context_2
test_hmac (when HMAC is supported)
benchmark_hash (when CONFIG_CRYPTO_LIB_BENCHMARK=y)
The initial use cases for this will be sha224_kunit, sha256_kunit,
sha384_kunit, sha512_kunit, and poly1305_kunit.
Add a Python script gen-hash-testvecs.py which generates the test
vectors required by test_hash_test_vectors,
test_hash_all_lens_up_to_4096, and test_hmac.
